You can set max.print to a larger value, e.g. options(max.print=Inf), 
and then the whole thing will print.  It won't be very useful to do that 
at the console, because most consoles don't have an infinite buffer, but 
if you're redirecting output to a file, it might be reasonable.

I don't understand this question.  Nothing about variab was lost, it 
just wasn't printed for you.  You can save it just like any other 
variable, using save(variab, file=...) to save in binary format.
